The Great Chemical Shark

The Great Chemical Shark is a predatory creature that lives in a place called the Bavarian Chemical Factory, and eats children who are held captive there. In the original timeline, it devoured a little girl named Madeline Pluto as a result of a felon named Bill Schmidt feeding her to it. In the current timeline, it has no significance, due to Madeline's nonexistence as a result of her parents, Victor and Karen, breaking up while they were dating.
